<P><STRONG>Functional Details</STRONG>
<P>
This module stacks a series of <I>n</I>-dimensional fields to form
a single (<I>n</I>+1)-dimensional field.
You can also use Stack to add a dimension to a single field (e.g.,
"stack" it from 2 dimensions to 3 dimensions).
Note that Stack does <I>not</I> accept partitioned data as
<TT><STRONG>input</STRONG></TT>.
<TABLE CELLPADDING="3">
<TR VALIGN="TOP"><TD><P><B><TT><STRONG>input</STRONG></TT>
</B></TD><TD><P>specifies the object(s) to be stacked.
The field(s) must have regular connections.
<BR>
If the parameter specifies a series, the location of the stacked field
in the new <TT><STRONG>dimension</STRONG></TT> is equal to the series
position of that field.

If the parameter specifies a group, then the location
of each member of the group
in the new
<TT><STRONG>dimension</STRONG></TT> will be 0, 1, ....

If the parameter specifies a field (rather than a field series), the
<I>n</I>-dimensional data is converted to
(<I>n</I>+1)-dimensional data, with the
value of the extra dimension set to zero.
<BR>
A dimension can be specified by number (from 0 to <I>n</I>
&#45; 1).
The first three can also be specified as <I>x</I>,
<I>y</I>, and <I>z</I>, respectively.
The default value is dimension 0 (zero).
